VEHICLE MICROCLIMATE PERSONALIZATION BASED ON OCCUPANT THERMOPHYSIOLOGY
A method of providing thermal conditioning for a vehicle occupant according to an example of the present disclosure includes determining a respective target temperature for each of a plurality of discrete OPZs. Each OPZ is associated with a different occupant body area. The determining is based on a difference between a first OTS indicative of a target heat flux for the occupant and a second OTS indicative of an estimated heat flux experienced by the occupant, wherein the respective target temperatures differ between the OPZs. The method includes providing thermal conditioning in each OPZ based on the target temperature for the OPZ, which includes utilizing at least one thermal effector in the OPZ. The method also includes receiving a temperature offset value for a particular one of the OPZs from the occupant, and adjusting the target temperature for the particular one of the OPZs based on the temperature offset value.
STEERING WHEEL AND HEAT-CONDUCTING DEVICE
A steering wheel and a heat-conducting device are provided. The steering wheel includes a body, a handle, a heating device, an electronic control unit, a heat-conducting member and a base. The handle is adjacent to the body, and the heating device is disposed in the handle and receives a driving signal to generate heat accordingly. The electronic control unit is electrically connected to the heating device through a driving wire, and provides the driving signal to the heating device. The heat-conducting member forms a waste heat path, and the heat-conducting member and the heating device are located at different locations in the handle. The base is connected to the electronic control unit, collects waste heat from the electronic control unit, and is connected to the heat-conducting member through a heat dissipation wire to transfer the waste heat to the heat-conducting member.
